To all whom it may concern:

Be it known that I, TEHEMTAN 'BAMAN- SHAW, a subject of the King of Great Britain and Ireland and Emperor of India, and a resident of Bombay, in the Bombay Presidency, British India, have invented certain new and useful Improvements in Keys for Regulating Sluices, I-Iydrants, and Stop- Cocks Aflixed to Water-Pipes, of which the following is a specification.

This invention relates to an improved key by means of which most of different kinds and sizes of sluices, hydrants and underground stop-cocks on water-pipes, can be regulated, without requiring several different keys for different kinds and sizes of sluices, hydrants and stop-cocks, afliXed to water-pipes.

In order that this invention may be more fully understood, I will now proceed to describe the same with reference to the accompanying drawings in which Figure 1 shows a full view of the improved key. Fig. 2 shows the improved lever or bar for turning the improved key. Fig. 3 shows partly in elevation and partly in section the tapering angular bushing. Fig. 4 shows partly in elevation and partly in section an enlarged View of the key head of the improved key. Fig. 5 shows a plan of the key head of the improved key as viewed from below.

Fig. 1 shows the improved key. It consists in the middle of a round bar R of sufiicient length and strength which is curved around at its upper extremity forming an eyelet E for inserting into it the lever bar shown separately in Fig. 2. At its lower extremity the bar R is enlarged into a head H Fig. 4 shows on alarge scale this key head (H partly in elevation and partly in section, and Fig. 5 shows on a large scale a plan of this key-head as viewed from below. In the bottom of this key-head a tapering angular socket N is provided as shown in Figs. 1 and 4. One or more holes, as may be found necessary, marked 0 O O O O 0 are pierced. at different levels as shown in Figs. 1 and 4, from the exterior side of the head H and reaching through to the inner walls of the tapering angular socket N These holes are provided with screw threads into which work thumbscrews marked T T T T T T all of the same size.

vWhile practically using the key, the aforesaid thumb-screws are drawn out sufficiently, and the tapering angular socket N is fitted onto the cap of a hydrant or a sluice, and if it be found to fit loosely the thumb-screws may be worked in, so as to tighten on the sides of the cap. The lever bar shown in Fig. 2, is then inserted in the eyelet E and the key may then be turned in either direction as required.

In case there is not enough space for turn ing the key together with the thumb screws T T T &c., inserted in it, these latter may be drawn out of their holes totally, and wherever the tapering angular socket N fits loosely over a hydrant or a sluice-cap, a bushing K K shown in Figs. 1, 4, 5, and also separately on a large scale partly in elevation and partly in section in Fig. 8, is inserted in the socket N to serve as apackingpiece, and the key may then be worked as usual. This bushing K K, is made of plate iron of suitable thickness.

The bushing and the thumb-screws abovementioned may be utilized together if desirable, for which vertical slits or openings V V V V, are provided in the four sides of the bushing, for the thumb-screws to pass through.

In order to render the key as above described useful also for regulating underground stop-cocks, small notches U U are provided in a straight line in the bottom of the key head H asshown in Figs. 1, 3, 4 and 5. Corresponding notches a 20 are also provided in the bushing K K. These notches U U, u, a, in practical use may be brought to bear on the handle D of the stop cock, and this handle may then be turned in either direction as required.

The bar or lever to be inserted in eyelet E of the improved key for turning it is shown in Fig. 2. It may have any type of extremities namely, plain, tapered, or arrow-head. Near the ends of this lever bar small holes L L should be provided, one near each 7 and underground stop-cocks on water-pipes,
